Vamp's seem better since they got Nerfed, the whole thing as a stealther is figuring out how you can counter them. If you're hitting that low with Legy's he probably has AoM, plus his self magic resist buff up.. Switch to physical dmg weps.

I do think they were OP before the nerf they recieved the other night, but between that and the new buffs for all players, they have balanced out.
